Comment 5 for bug 1032208

Note: I'm not 100% sure this is ready for prime time.

If the old, bad approach created:

 id | source | field | value
-----+--------+-------+----------------------------------------------------------------------
 178 | 47 | 5 | Concertos, piano
 179 | 47 | 5 | Rapsodie sur un thème de Paganini, piano, orchestra
 180 | 47 | 5 | Concertos, piano Rapsodie sur un thème de Paganini, piano, orchestra
(3 rows)

and the new approach creates:

 id | source | field | value
-----+--------+-------+----------------------------------------------------------------------
 180 | 47 | 5 | Concertos, piano Rapsodie sur un thème de Paganini, piano, orchestra
(1 rows)

... then it seems like there is a loss of granularity for search purposes (e.g. searching for "starts with Rapsodie").

More testing needed?
